Subject: [PATCH] UN-2874 Address CodeRabbit review: Add lock TTL and error
 checking for destination processing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add lock TTL (10 min default) to prevent deadlock if worker crashes during destination processing
- Add error check before marking DESTINATION_PROCESSING SUCCESS to ensure no false success status
- Add DESTINATION_PROCESSING_LOCK_TTL_IN_SECOND=600 to workers/sample.env
